I wonder if I can legaly use the drive as an online backup storage (containing "buckets" with client-side encrypted content - mostly photos; encryption will obviously prevent from smart de-duping in the cloud). I was trying to find "fineprint" (like S3 and Amazon Glacier), no luck. It's just too good to be true, I still can't believe the 1Tb has such low price. Another interesting thing: SLA (do they have disaster recovery setup, etc.)
